Purchased this for my son. He always uses Amsoil products in his F-250 and is pleased with their performance.

Seems to be doing very well. There was an audible change in engine noise it sounded smoother and ran happier on my 2019 ram 3500

have been using the 15W 40 Amsoil diesel oil since my 2020 GMC 3500 was new. No oil consumption, changing the engine oil every 10,000 miles.

Comes quick and great oil.

I only use the AMSOIL diesel oil in my truck. At 300,000 miles, I replaced the injectors and when the valve cover was removed, the all of the metal components looked as clean as if the engine was brand new.

Great product for a great price.

This oil holds up in our Phoenix so good. I have never had any issues summer or winter.thanks amsoil

I own a 2020 Ram 2500 6.7L Cummins diesel, and I was tired off the dealership. I switched because of Amsoil brand name, and the unbelievable amount of positive reviews. The ordering and shipping were easy and very quick. The product and shipping box were not damaged, hint at another retail shipping giant. I cannot comment on how the oil is working, as it has not even been 500 miles since my oil change. I will buy again and have!

I use this oil for my F350. Life of the oil is great. Keeps my motor running smoothly. Can't ask for better.

The only oil and filter I use in any of my vehicles is Amsoil! This truck gained about 1 MPG after the 1st oil change with Amsoil! To me Amsoil means less maintenance more miles and hassle free service! I order on-line and have it within 3 days!

I used this oil for a Kioti CK2620 hst compact diesel tractor. After changing out the oil the engine definitely ran quieter. My decision to use this oil was based on reading countless entries on light equipment forums and also reviews of many Amsoil users.

I believe in superior lubrication protection for my 6.7 Cummins.

oil test show wear on engine is almost none. Much better than what I used before. Also, the gear lube for my Polaris general has my front and rear differential quiet and clean. Overall I use AMSOIL in every motor on the property.

After speaking with a friend that uses this product, and several mechanics, I use the Signature Series, fully synthetic oil along with a stiction eliminator in my Chevy Duramax. The product has served me well as reported from Blackstone Labs at every oil change.

excellent oil

Super quick delivery, almost next day and great product for a great price with my preferred customer discount

I’ve have 2017 6.7 with 109,600 miles on it. CP4 grenaded and in the process skipped the crank gear. Front cover was removed to retime which give me a chance to look inside the engine. It was clean as hell with no sludge buildup at all. All that’s been used is Amsoil 5-40 oil. I swear by this product.

Use it in my 2001 dodge ram 2500 24v 5.9 cummins. Works great. I recommend getting the preferred costumer account upgrade, it makes it a fair bit cheaper

there isn't an oil better .

Best oil…. Period!
